Description

The present disclosure relates to an adsorber that utilizes a function of an adsorbent to adsorb a medium to be adsorbed, evaporates a refrigerant, and exerts a refrigerating capacity by its latent heat of vaporization.

Conventionally, as this type of adsorber, there is an adsorber described in Patent Document 1. The adsorber described in Patent Document 1 includes a closed container in which an adsorbent that adsorbs a refrigerant is housed. The airtight container defines a condensation/evaporation surface layer containing a refrigerant and an adsorption/desorption surface layer containing an adsorbent. The condensation/evaporation surface layer and the adsorption/desorption surface layer are communicated with each other via a communication portion. A first circulating water channel and a second circulating water channel through which the respective heat exchange media flow are arranged above and below the outside of the condensation/evaporation surface layer and the adsorption/desorption surface layer, respectively.

In the adsorber described in Patent Document 1, during the adsorption step, heat exchange between the heat exchange medium flowing through the second circulating water channel and the liquid phase refrigerant in the condensation/evaporation surface layer causes liquid phase refrigerant in the condensation/evaporation surface layer. Evaporates. Due to the latent heat of vaporization during evaporation of the liquid phase refrigerant, the heat exchange medium flowing through the second circulating water channel is cooled. Further, at this time, in the adsorption/desorption surface layer, the adsorbent adsorbs the vaporized vapor-phase refrigerant to promote evaporation. At this time, since the adsorbent generates heat when adsorbing the vapor phase refrigerant, the temperature of the adsorbent rises. When the temperature of the adsorbent rises, the adsorption capacity of the adsorbent decreases. In order to suppress this, heat exchange is performed between the heat exchange medium flowing through the first circulation water channel and the adsorbent, whereby the temperature rise of the adsorbent is suppressed.

By the way, in the adsorber described in Patent Document 1, the temperature of the heat exchange medium flowing through the first circulating water passage increases toward the downstream side of the first circulating water passage during the adsorption process. Therefore, the adsorbing ability of the adsorbent in the adsorbing/desorbing surface layer decreases toward the downstream side of the first circulation water channel. On the other hand, the temperature of the heat exchange medium flowing through the second circulation water channel decreases toward the downstream side of the second circulation water channel. Therefore, the liquid-phase refrigerant in the condensation/evaporation surface layer becomes less likely to evaporate toward the downstream side of the second circulation water channel.

As described above, in the adsorber described in Patent Document 1, in the adsorption/desorption surface layer and the condensation/evaporation surface layer, the adsorption capacity tends to decrease on the downstream side of each of the first circulation water channel and the second circulation water channel. is there. This is a factor that reduces the refrigerating capacity of the adsorber.

The tank portion 621 of the evaporation/condensation core portion 62 is connected to the four-way valve 74.

Next, an operation example of the refrigerator 10 of the present embodiment will be described.
When the four-way valves 71 to 74 are in the connected state shown in FIG. 1, the first heat medium circulates between the adsorption core portion 51 of the first adsorber 50 and the heat source 20. Therefore, the high-temperature first heat medium whose temperature has risen in the heat source 20 flows through the adsorption core portion 51. When the first heat medium flows through the adsorption core portion 51, heat exchange is performed between the first heat medium and the adsorbent 54, so that the adsorbent 54 is heated. As a result, the medium to be adsorbed is desorbed from the adsorbent 54.

Further, when the four-way valves 71 to 74 are in the connected state shown in FIG. 1, the second heat medium circulates between the evaporation/condensation core part 52 of the first adsorber 50 and the second heat dissipation part 42. Therefore, in the evaporation/condensation core portion 52, the second heat medium cooled by exchanging heat with the air in the second heat dissipation portion 42 flows. When the second heat medium flows through the evaporation/condensation core portion 52, the second heat medium absorbs the heat of the adsorption medium desorbed from the adsorbent 54, so that the surface of the evaporation/condensation core portion 52 adsorbs the adsorption medium. Is condensed. The adsorption target medium condensed on the surface of the evaporation/condensation core portion 52 is carried by the carrying member 55. In this way, the evaporation/condensation core portion 52 functions as a portion that promotes desorption of the medium to be cooled from the adsorbent 54.

On the other hand, when the four-way valves 71 to 74 are in the connected state shown in FIG. 1, the second heat medium circulates between the evaporation/condensation core portion 62 of the second adsorber 60 and the cold heat generator 30. When the second heat medium flows through the evaporation/condensation core portion 62, heat exchange is performed between the adsorbed medium carried by the carrying member 65 and the second heat medium, whereby the object carried by the carrying member 65 is carried out. The adsorption medium evaporates. The second heat medium is cooled by the latent heat of vaporization generated at this time. The cooled second heat medium flows through the cold heat generator 30, whereby cold heat is generated from the cold heat generator 30. The adsorbed medium evaporated from the supporting member 65 is adsorbed by the adsorbent 64 of the adsorbing core 61.

Further, when the four-way valves 71 to 74 are in the connected state shown in FIG. 1, the first heat medium circulates between the adsorption core portion 61 of the second adsorber 60 and the first heat radiation portion 41. Therefore, the first heat medium cooled by exchanging heat with the air in the first heat dissipation part 41 flows through the adsorption core part 61. When the first heat medium flows through the adsorption core portion 61, the heat of the adsorbent 64 is absorbed by the first heat medium, whereby the adsorbent 64 is cooled. As a result, the adsorbability of the adsorbed medium by the adsorbent 64 is enhanced.

In this way, when the four-way valves 71 to 74 are in the connected state shown in FIG. 1, in the first adsorber 50, the adsorbed medium is desorbed from the adsorbent 54 by heat exchange with the first heat medium, and The desorbed medium to be adsorbed is condensed. In the second adsorber 60, the adsorbed medium is evaporated from the carrying member 65, and the evaporated adsorbed medium is adsorbed by the adsorbent 64.

The refrigerator 10 maintains the connection state of the four-way valves 71 to 74 in the state shown in FIG. 1 for a predetermined time and then switches the connection state of the four-way valves 71 to 74 to the state shown in FIG. 2. As a result, the second heat medium circulates between the evaporation/condensation core portion 52 of the first adsorber 50 and the cold heat generator 30. When the second heat medium flows through the evaporation/condensation core portion 52, heat exchange is performed between the adsorbed medium carried by the carrying member 55 and the second heat medium, whereby the object carried by the carrying member 55 is carried out. The adsorption medium evaporates. The second heat medium is cooled by the latent heat of vaporization generated at this time. The cooled second heat medium flows through the cold heat generator 30, whereby cold heat is generated from the cold heat generator 30. The adsorbed medium evaporated from the supporting member 55 is adsorbed by the adsorbent 54 of the adsorbing core 51.

Further, when the four-way valves 71 to 74 are in the connected state shown in FIG. 2, the first heat medium circulates between the adsorption core portion 51 of the first adsorber 50 and the first heat radiation portion 41. Therefore, the first heat medium cooled by exchanging heat with the air in the first heat dissipation part 41 flows through the adsorption core part 51. When the first heat medium flows through the adsorption core portion 51, the heat of the adsorbent 54 is absorbed by the first heat medium, whereby the adsorbent 54 is cooled. As a result, the adsorbability of the adsorbed medium by the adsorbent 54 is enhanced.

On the other hand, when the four-way valves 71 to 74 are in the connected state shown in FIG. 2, the first heat medium circulates between the adsorption core portion 61 of the second adsorber 60 and the heat source 20. Therefore, the high-temperature first heat medium whose temperature has risen in the heat source 20 flows through the adsorption core portion 61. When the first heat medium flows through the adsorption core portion 61, the heat of the first heat medium is transferred to the adsorbent 64, so that the adsorbent 64 is heated. As a result, the medium to be adsorbed is desorbed from the adsorbent 64.

Further, when the four-way valves 71 to 74 are in the connected state shown in FIG. 2, the second heat medium circulates between the evaporation/condensation core portion 62 of the second adsorber 60 and the second heat radiation portion 42. Therefore, in the evaporation/condensation core portion 62, the second heat medium cooled by exchanging heat with the air in the second heat radiation portion 42 flows. When the second heat medium flows through the evaporation/condensation core portion 62, the second heat medium absorbs the heat of the adsorption medium desorbed from the adsorbent 64, so that the surface of the evaporation/condensation core portion 62 receives the adsorption medium. Is condensed. The adsorption target medium condensed on the surface of the evaporation/condensation core portion 62 is carried by the carrying member 65. In this way, the evaporation/condensation core portion 62 functions as a portion that promotes desorption of the cooled medium from the adsorbent 64.

In this way, when the four-way valves 71 to 74 are in the connected state shown in FIG. 2, in the second adsorber 60, the adsorbed medium is desorbed from the adsorbent 64 by heat exchange with the first heat medium, and The desorbed medium to be adsorbed is condensed. In the first adsorber 50, the adsorbed medium is evaporated from the carrying member 55, and the evaporated adsorbed medium is adsorbed by the adsorbent 54.

The refrigerator 10 maintains the connection state of the four-way valves 71 to 74 in the state shown in FIG. 2 for a predetermined time, and then switches the connection state of the four-way valves 71 to 74 to the state shown in FIG. After that, the refrigerator 10 continuously generates cold heat from the cold heat generator 30 by switching the connection state of the four-way valves 71 to 74 between the state shown in FIG. 1 and the state shown in FIG. 2 at a predetermined cycle. Let

By the way, as shown in FIG. 2, when the adsorbed medium evaporates in the first adsorber 50, in the first adsorber 50, the first heat medium flowing in the adsorbent core portion 51 and the evaporation/condensation core portion 52 are separated from each other. The flowing second heat medium flows in opposition. As a result, in the evaporation/condensation core portion 52, the tubular member 523b arranged on the downstream side in the flow direction of the second heat medium is closer to the tubular member 523b arranged on the upstream side in the flow direction of the second heat medium. But the temperature drops. Therefore, the medium to be adsorbed is less likely to evaporate in the carrying member 55 of the tubular member 523b than in the carrying member 55 of the tubular member 523a. Further, in the adsorption core portion 51, the temperature of the tubular member 523a arranged on the downstream side in the flow direction of the first heat medium is higher than that of the tubular member 513b arranged on the upstream side in the flow direction of the first heat medium. Rise. Therefore, the adsorbent 54 of the tubular member 513b is more likely to adsorb the medium to be adsorbed than the adsorbent 54 of the tubular member 513a.

That is, in the first adsorber 50, the downstream portion of the evaporation/condensation core portion 52, which is less likely to evaporate, and the upstream portion of the adsorption core portion 51, which is more likely to adsorb, face each other. Further, the upstream side portion of the evaporation/condensation core portion 52 where evaporation is likely to occur and the downstream side portion of the adsorption core portion 51 where it is difficult to adsorb face each other. This makes it possible to balance the adsorption and evaporation of the adsorbed medium in the first adsorber 50, so that the adsorbability of the adsorbed medium can be improved.

In addition, as shown in FIG. 3, in the first adsorber 50, the partition plate 56 divides the internal region of the closed container 53 into a first internal region A11 and a second internal region A12. This can suppress the inflow and outflow of the adsorbed medium between the first internal region A11 and the second internal region A12, so that the adsorptivity of the adsorbed medium can be further improved.

Similarly, as shown in FIG. 1, when the adsorbed medium evaporates in the second adsorber 60, in the second adsorber 60, the first heat medium flowing in the adsorbent core section 51 and the evaporation/condensing core section 52. And the second heat medium flowing through it flows in opposition. Therefore, the second adsorber 60 can also obtain the same operation and effect as the first adsorber 50.

According to the first adsorber 50 and the second adsorber 60 of the present embodiment described above, the actions and effects shown in the following (1) to (4) can be obtained.
(1) In the first adsorber 50, in the closed container 53, the first heat medium flowing through the adsorption core portion 51 and the second heat medium flowing through the evaporation/condensation core portion 52 flow so as to face each other. Also in the second adsorber 60, in the closed container 63, the first heat medium flowing in the adsorption core portion 61 and the second heat medium flowing in the evaporation/condensation core portion 62 flow so as to face each other. This makes it possible to balance the adsorption and evaporation of the adsorbed medium in the first adsorber 50 and the second adsorber 60, so that the adsorbability of the adsorbed medium can be improved.

(2) The first adsorber 50 includes a partition plate 56 that partitions the inside of the closed container 53 into a first internal area A11 and a second internal area A12. This can suppress the inflow and outflow of the adsorbed medium between the first internal region A11 and the second internal region A12, so that the adsorptivity of the adsorbed medium can be further improved. Further, since the second suction device 60 also includes the partition plate 66 having the same function, the same operation and effect can be obtained.

(3) The partition plate 56 of the first adsorption device 50 and the partition plate 66 of the second adsorption device 60 are made of a heat insulating material. As a result, heat transfer between the first internal region A11 and the second internal region A12 can be suppressed, so that the adsorptivity of the adsorbed medium can be further improved.
(4) The tubular members 513a and 513b of the adsorption core portion 51 of the first adsorption device 50 are orthogonal to the tank portions 510, 511, 520 and 521. Further, the tubular members 613a, 613b of the adsorption core portion 61 of the second adsorption device 60 are orthogonal to the tank portions 610, 611, 620, 621. As a result, the heat transfer area of each of the first adsorber 50 and the second adsorber 60 can be increased, so that the adsorption performance of the first adsorber 50 and the second adsorber 60 can be improved.

In addition, the above-mentioned embodiment can also be implemented in the following forms.
As shown in FIG. 4, the partition plate 56 of the first suction device 50 may be provided with slits 560 extending in a direction orthogonal to both the vertical direction and the horizontal direction. The slit 560 is arranged between the adsorption core portion 51 and the evaporation/condensation core portion 52 in FIG. According to such a configuration, heat leakage between the adsorption core portion 51 and the evaporation/condensation core portion 52 via the partition plate 56 is suppressed, so that the adsorption performance of the first adsorber 50 can be further improved. You can Further, by forming similar slits in the partition plate 66 of the second suction device 60, the same action and effect can be obtained.

-As shown in Drawing 5, the 1st adsorption machine 50 may be the structure which does not have carrying member 55. In this case, when the adsorbed medium is condensed by heat exchange with the evaporation/condensation core part 52, when the condensed adsorbed medium is stored in the bottom wall part 533 of the closed container 53, the evaporation/condensation core part 52 is absorbed. Will be immersed in. The same configuration can be applied to the second adsorber 60.

-As shown in Drawing 6, closed container 53 of the 1st adsorption machine 50 may be divided into a plurality of internal fields by a plurality of partition plates 56. The same configuration can be applied to the second adsorber 60.
-As shown in Drawing 7, the 1st adsorption machine 50 may be constituted by a plurality of adsorption parts 50a and 50b. Each of the suction parts 50a and 50b has a structure in which the partition plate 56 is removed from the structure of the first suction device 50 shown in FIG. The suction core portions 51 of the suction portions 50a and 50b are connected to each other via a flow path 75a. Further, the respective evaporation/condensation core parts 52 of the adsorption parts 50a and 50b are connected to each other via a flow path 75b. Even with such a configuration, since the inner region of the closed container 53 of the suction unit 50a and the inner region of the closed container 53 of the suction unit 50b are substantially separated, the first suction unit having the partition plate 56 is formed. The same operation and effect as the container 50 can be obtained. Similarly, the second adsorber 60 may also be composed of a plurality of adsorbing portions 60a and 60b.

-The adsorption core part 51 and the evaporation/condensation core part 52 of the 1st adsorption device 50 may consist of a heat exchange part of a drone cup type. For example, the suction core part 51 may have a structure as shown in FIG. As shown in FIG. 8, the suction core portion 51 is configured by stacking a plurality of drone cup plates 57. In this case, the partition plate 56 can be easily provided on the suction core portion 51 only by sandwiching the partition plate 56 between the adjacent drone cup plates 57, 57. The corrugated member provided inside the tubular members 513a and 513b is an inner fin. Further, even when the evaporation/condensation core part 52 is formed by a heat exchange part of a drone cup type, the partition plate 56 can be easily provided on the evaporation/condensation core part 52. Therefore, the first adsorber 50 of the above embodiment can be easily manufactured. Similarly, if the adsorption core portion 61 and the evaporation/condensation core portion 62 of the second adsorber 60 are configured by a drone cup type heat exchange portion, the second adsorber 60 of the above embodiment can be easily manufactured. ..
